Old, Ripped and Brittle Poly Moisture Barrier.

New Poly Moisture Barrier.
National Exterminating has a talented crew with years of experience in understructure repair. National Exterminating is a licensed, fully insured Class C contractor and we are more than capable to handle home repairs and projects. Crawlspace repairs can be very challenging for homeowners due to the lack of space along with the existing wires, plumbing, utility lines, sprinkler systems and HVAC systems. Our techniques for working in these confined spaces have been perfected over time. National Exterminating works closely with city officials as needed to ensure adherence to local code requirements.
We are very proud of our skilled in-house team of technicians eliminating the need to hire subcontractors for most jobs. Subcontractors will only be brought in as needed to complete electrical portions of our projects.
From moisture control with Hybrid Controlled Crawlspace Encapsulation systems to repairing and replacing crawlspace structural components, National Exterminating can develop an individualized plan to ensure the health, comfort and protection of each customer’s home.
